CLEANING NOZZLE.

application nlea'october s1, 192s. ser'iarm, 671,893.

The present invention relates to cleaning nozzles.

More particularly, the present invention relates to cleaning nozzles suchas are use for conveying cleaning liquid to relatively inaccesible places, as`for instance, the parts v,

of a locomotive. It has been 'common prac'- tice` to use mechanism for such purposes which comprises a nozzle for mixing air and cleaning fluid, which nozzle is mounted upon the ends of'elongated pipes carrying said air and cleaning liquid. In order that the cleaning nozzle may be readily manipulated i't has been common practice to provide supply' pipes of as small weight as will serve the purpose and diiiiculty has been encountere by lreason of lack4 of rigidity in the cleaning structure.

An object of the present invention to 'rovide a cleaning nozzle and connections therefor whichwill be rigid though light in construction.

A further object is to provide a structure which will combine rigidity with ease of Further obj tion proceeds.

Referring-tothe drawings#- Figure 1 is a. view in side elevation of one embodiment of the invention;

Figure 2 is a tgp Aplan view ofthe structure shown in' Figure l;

Figure 3 is a sectional view taken on Ithe planedindicated by the line 3-3 of Figure ;3n A Figure 4 is an end elevation of the. structure ,illustrated in the preceding figures.

, The numeral 1 indicates a cleaning nozzle,I nozzle'is provided with a diaphragm ects will appear as the descripv'separates the nozzle into two elongated passageways 3 and 4, which passage-ways 3 and-- 4 communicate with. the mixing chamberl 5.

Said mixing chamber 5 communicates with the discharge opening 6 inthe endportion 7 of thenozzle 1. 'The end portion 7 and the discharge opening 6 may be of flared shape laterally of the nozzle, vwherebv a flat stream is projected from the opening 6. i

he rear wall of the nozzle 1 is provided -with a-pair of apertures 8, 8 which may be screw threaded for the recepti`o1v 1' .jof 'the pipes 9,-9.- One of said pipes 9 wil mmuncate with the passage-way 3 and ma vsupply air to said'- paage-way, The o pipes 9 will communicate with the( on the interior thereof, which diaphragmv lstream from the'nozzle. -ticularly adapted for use water, .suspension of said v way 4 and may supply water an` oil or other cleaning iiuid to the passage-way 4.'

d The bottom of the nozzle 1 will be provided with a removable plug 10 for .cleanlng purposes.

Connected with the rear wall of the nozzleu 1 is the web 11 which forms the support for the pair of braces 12, 12. Each of said braces v12, 12 is provided with anfaperture 13 for receiving one of the pipes 9, 9, Each of pi es 9, '9iwill be more or less closely engage byythe braces 12, 12, whereby to reduce shaking of the nozzle relative to said pipes 9,

9 to a minimum. Each of the braces 12, 12

will serve as an abutment, not only ofor preventing shaking, but for preventing sagging of the'nozzle relative to the pipes 9', 9. It

will be noted that a nozzle is provided having almain body portion which has a lower floor portion 13, said floor portion being substantially fiat throughout the greater part of its length. From the end portion 7 ex-` tends an upwardly curved wall 14 terminating in the rear wall of the nozzle, which upwardly curved wall forms with the partition 2 the converging passageway 3. It will thus be seen that I have provided a nozzle in which the oil and water mixture is di-l rectedfstraight to the'nozzle outlet, and that the airis directed t'o the oil and water mixvture in such a'way that abrupt turns in the air streamare avoided. Due tothe flat bottom 13, abrupt turns in the iiow of oil and water are also avoided. By reason of the structure illustrated, therefore, a rigid structure is vprovided which servesthe purpose for which it is intended with great eff fectiveness. Byreason'of the fact that the parts are reinforced, as'described, said `parts may be considerably elongated and, though made of lightweight, will not undulysag or shake inservice. -VIt will be noted that, the' partition 2 extends-forwardly to such an extent that the mixturev of water and oil lfrom y the passageway 4 and the air from passageway-3 occurs just before thel ejection of th'e in the cleaning of locomotives, inasmuch .'as` it A provides stream comprisingL a -mixture of oil and by'the action ofthe stream of'air thereon just before the from the nozzle. In or be erthat, this may A assageloo 'The nozzle is parthe oil being reduced to a colloidal Y.

done most efficiently, it is desirable that the colloidal suspension of oil and Water be applied to the surface to be cleaned as soon after such suspension is formed as is possi- -ble. Itfis for this purpose that the elongated partition 2 is provided in the body of the nozzle which separates the stream of air .from the stream of oil and Water until the moment of ejection. Attention is directed to the structure of the body part which is elongated horizontally at its forward portion and elongated vertically at its rear portion. Attention is also directed to the downward turning of the upper and lower Walls of lthe end 7 ofthe nozzle, the purpose of this feature being todirect the stream against'the parts of the locomotive to be cleaned when the pipes 9 are held at an ,angle to the horizontal, as is customarily done.

Though a preferred' embodiment of the present invention has been described in detail, it Will be clear to those skilled in the art, that many modifications may be made Without departing from the spirit of the inf housing being closed at its rear end by a Wall in substantially a single plane, a division member Within said housing extending forwardly from said rear Wall to a point adjacent the exit from the nozzle, said wall being provided with orifices for the reception of Huid conveying p ipes, bracing means fork said' pipes, said bracing means comprisina supporting portion extending outwar ly from the Wall ata point between said orifices, and a bracing Wall substantially parallel to said rear Wall and provided with corresponding apertures for the Huid conveying 5 pipes.
